Subject: using prefixes via their extended command names
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a0100dd30014403bb4f71f1b5fcc3ec851acea2f;p=nethack

using prefixes via their extended command names

Trying to use #reqmenu/#rush/#run/#fight prefixes by their extended
command names didn't work because rhack()'s post-processing was stuck
dealing with the entry for the '#' key after using doextcmd() to run
any command.  Use a static variable (actually a global one since I put
it into struct g) to notify rhack() of the command that ultimately got
executed.
